Change log file for Exim from version 4.21
-------------------------------------------
TF/03 Added the control = fakedefer ACL modifier.
-TF/04 Added the ratelimit ACL condition. See NewStuff for details.
+TF/04 Added the ratelimit ACL condition. See NewStuff for details. Thanks to
+ Mark Lowes for thorough testing.
TK/02 Rewrote SPF support to work with libspf2 versions >1.2.0.
SC/07 Eximstats: removed tabs and trailing whitespace.
+TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller.
+
+TK/06 MBOX spool code: Add real "From " MBOX separator line
+ so the .eml file is really in mbox format (even though
+ most programs do not really care). Patch from Alex Miller.
+
+TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
+ The latter is generated from $received_to and is only set if the
+ message has one envelope recipient. SA can use these headers,
+ obviously out-of-the-box. Patch from Alex Miller.
+
+PH/08 The ${def test on a variable was returning false if the variable's
+ value was "0", contrary to what the specification has always said!
+ The result should be true unless the variable is empty.
+
+PH/09 The syntax error of a character other than { following "${if
+ def:variable_name" (after optional whitespace) was not being diagnosed.
+ An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
+ accidental colon was present, for example, could give incorrect results.
+
+PH/10 Tidied the code in a number of places where the st_size field of a stat()
+ result is used (not including appendfile, where other changes are about
+ to be made).
+
+PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
+ This involved changing a lot of size variables from int to off_t. It
+ should work with maildirs and everything.
+
+TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of
+ spamd dying while we are connected to it.
+
+TF/05 Fixed a ${extract error message typo reported by Jeremy Harris
+ <jgh@wizmail.org>
+
+PH/12 Applied Alex Kiernan's patch for the API change for the error callback
+ function for BDB 4.3.
+
+PH/13 Changed auto_thaw such that it does not apply to bounce messages.
+
+PH/14 Imported PCRE 6.0; this was more than just a trivial operation because
+ the sources for PCRE have been re-arranged and more files are now
+ involved.
+
+PH/15 The code I had for printing potentially long long variables in PH/11
+ above was not the best (it lost precision). The length of off_t variables
+ is now inspected at build time, and an appropriate printing format (%ld
+ or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
+ to be "long long int" or "long int". This is needed for the internal
+ formatting function string_vformat().
+
+PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
+ the configuration file to be ":syslog", then the script "guesses" where
+ the logs files are, rather than using the compiled in default. In our
+ case the guess is not the same as the compiled default, so the script
+ suddenly stopped working when I started to use syslog. The patch checks
+ to see if log_file_path is "". If so, it attempts to read it from exim
+ with no configuration file to get the compiled in version, before it
+ falls back to the previous guessing code."
+
+TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with
+ implementing BATV in an Exim configuration. See NewStuff for the gory
+ details.
+
+PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and
+ Makefile that are specific to HP-UX.
+
+PH/18 If the "use_postmaster" option was set for a recipient callout together
+ with the "random" option, the postmaster address was used as the MAIL
+ FROM address for the random test, but not for the subsequent recipient
+ test. It is now used for both.
+
+PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
+ patch removes a few documentation additions to RFC 3028, because the
+ latest draft now contains them. It adds the new en;ascii-case comparator
+ and a new error check for 8bit text in MIME parts. Comparator and
+ require names are now matched exactly. I enabled the subaddress
+ extension, but it is not well tested yet (read: it works for me)."
+
+PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
+ rework some of the code of TK/09 above to avoid the hardwired use of
+ "%lld" and "long long". Replaced the call to snprintf() with a call to
+ string_vformat().
+
+PH/21 Added another message to those in 4.51/PH/42, namely "All relevant MX
+ records point to non-existent hosts".
+
+PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
+ experimental DomainKeys support:
+
+ (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
+ (2) On an error such as an illegally used "control", the wrong name for
+ the control was given.
+
+ These problems did NOT occur unless DomainKeys support was compiled.
+
+PH/23 Added daemon_startup_retries and daemon_startup_sleep.
+
+PH/24 Added ${if match_ip condition.
+
+PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
+ databases so that it will be absolutely obvious if a crash occurs in the
+ DB library. This is a regular occurrence (often caused by mis-matched
+ db.h files).
+
+PH/26 Insert a lot of missing (void) casts for functions such as chown(),
+ chmod(), fcntl(), and sscanf(). These were picked up on a user's system
+ that detects such things. There doesn't seem to be a gcc warning option
+ for this - only an attribute that has to be put on the function's
+ prototype. I'm sure I haven't caught all of these, but it's a start.
+
+PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
+ specify a transport. However, if an address that was verified by such a
+ router was the subject of a callout, Exim crashed because it tried to
+ read the rcpt_include_affixes from the non-existent transport. Now it
+ just assumes that the setting of that option is false. This bug was
+ introduced by 4.51/PH/31.
+
+PH/28 Changed -d+all to exclude +memory, because that information is very
+ rarely of interest, but it makes the output a lot bigger. People tend to
+ do -d+all out of habit.
+
+PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the
+ code in os-type was giving problems when libc.so lives in lib64, like on
+ x86_64 Fedora Core.
+
+PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
+ aren't the modern standard, and it seems that some systems' include files
+ don't always have them. Exim was already checking for some of the newer
+ ones like T_AAAA, and defining it itself. I've added checks for all the
+ record types that Exim uses.
